What codes are setting?
I attached a diagram of the charging system. Can you tell me if the alternator has 12v on one and a ground on the other? What voltage is the alternator outputting?
I'm sorry but if the battery light is on then it's not charging and if you have replaced the PCM, alternator, battery and it's still on then the alternator isn't charging and I would try and repair the not charging before I would worry about the light... The alternator should be charging 14v @ idle and if not you will need to make the check's I provided..
Glad I could help and thank you for the positive rating,
